摘　　要：影响开关磁阻电机推广的主要因素之一就是其转矩脉动较大。为了降低转矩脉动,在传统四相8/6极开关磁阻电机基础上,提出了四相16/12极开关磁阻电机的新型结构。电机控制单元采用处理速度较强的STM32F051C作为该型电机的控制芯片,并通过直接转矩控制算法对电机转矩进行控制。通过在测功机上的空载和加载试验,得出电机在不同工作状态下的绕组电流波形,经测试分析,该系统调速性能良好。One of the main factors affecting the promotion of switched reluctance motor is its large torque ripple. In order to reduce the torque ripple, a new structure of the four phase 16/12 pole switched reluctance motor is presented based on the traditional four phase 8/6 pole switched reluctance motor. Motor control unit adopts STM32F051 c with the strong processing speed as control chip, the motor torque is controlled by the direct torque control algorithm. Through no-load and load tests on the dynamometer, the motor winding current waveform is obtained under different working conditions. Testing shows that the system has performance. good speed regulation
